Abstract Hexavalent chromium (Cr (VI)) is a widespread, toxic contaminant in the
environment. Owing to the increasingly strict requirements for green production and …

Groundwater resources in California represent a confluence of high-risk factors for
hexavalent chromium contamination as a result of industrial activities, natural geology, and …

Climate change has threatened global food security. There is an unrelenting need to
understand various factors associated with abiotic stress and their response, adaptability …

Chromium (VI) produced from the oxidation of indigenous Cr (III) minerals is increasingly
being recognized as a threat to groundwater quality. A critical determinant of Cr (VI) …

Abstract Hexavalent chromium (Cr (VI)) groundwater usually exists in shallow aquifers
related to ultramafic and serpentine formations, but knowledge of the genesis of dissolved …

Chromium speciation in naturally contaminated soils appears more complex than spiked
studies have shown. This study characterized Cr speciation (oxidation states; availability; …

Previously reported stable Cr isotopic fractionation in Archaean paleosols and iron
formations (IFs) have been interpreted as a signature of oxidative weathering of Cr (III) to Cr …

Chromium is abundantly and primarily present as Cr (III) in ultramafic rocks and serpentine
soils. Chromium (III) oxidation involving chromite (FeCr2O4) via interactions with birnessite …

Reaction path modelling of serpentinite dissolution in meteoric water was performed,
varying Fe 2 O 3/(FeO+ Fe 2 O 3) weight ratios of serpentine and reproducing the analytical …

Even though the Amazon region is widely studied, there is still a gap regarding Cr exposure
and its risk to human health. The objectives of this study were to 1) determine Cr …
